Cause
Due to different software ver-
sions, I/O board and amplifier
board are only partially compati-
ble (possibly restricted function-
ality).
!
Note!

– This condition can occur if only
one electronics board has
been exchanged; the extended

available. The previously exist-
ing software functionality is still
working and the measurement
possible.

tions (measuring mode for pulsat-
ing flow) could not be cleared or
output within 60 seconds.
